Cardiff boss Dave Jones is again likely to be without Craig Bellamy for the home clash against Crystal Palace, although Seyi Olofinjana stands a marginally better chance of being involved.
The former Southampton manager is desperately looking to get the key duo back in action, but knows he cannot rush their rehabilitation and may well be forced to see them make a full return after the international break, which follows Saturday`s trip to Barnsley.
Bellamy has been sidelined for the past three weeks with a troublesome knee injury, while influential midfielder Olofinjana has been missing for a fortnight with a thigh problem.
That may mean the pair`s return coincides with that of Danny Drinkwater (thigh) and Michael Chopra (ankle), who are both targeting the Severnside derby against Bristol City on October 16 to make their comebacks.
Jones must decide whether to keep faith with Tom Heaton after he made his first league start of the season in Saturday`s last-gasp 2-1 win over Millwall, demoting David Marshall to the bench.
Marlon King is likely to make his first start for the Sky Blues.
The striker made an impressive contribution when he came off the bench to make his debut in Saturday`s 2-1 reverse to Preston, inspiring a fightback which came close to snatching a deserved share of the spoils.
After the game, manager Aidy Boothroyd said: "He (Marlon) has given himself a good chance of starting on Tuesday. He's focused and very much looking forward to playing a key part in what we are doing here."
The Sky Blues boss may opt to make make or two changes elsewhere following Saturday`s defeat, although he was anything but disappointed with his side`s efforts as they dominated North End only to be thwarted by keeper Andy Lonergan.
Gary McSheffrey, Danny Ward, David Bell and Michael McIndoe are all pushing for starts, but the likes of Freddy Eastwood (knee), James McPake (shin) and Gary Deegan (ankle) remain in the stands.
